The primary purpose of test administration is to ensure that the test is conducted in a fair and standardized manner so that all test takers have an equal opportunity to demonstrate their knowledge and skills.

The key responsibilities of a test administrator include providing clear instructions to the test takers, ensuring that the testing environment is conducive to optimal performance, and monitoring the test takers to ensure that they are following the rules.

Objective scoring is based on predetermined criteria, while subjective scoring is based on the judgment of the scorer. Objective scoring is generally more reliable than subjective scoring, but it is not always more valid.

Common methods of objective scoring include multiple-choice questions, true-false questions, and matching questions.

Common methods of subjective scoring include essay questions, performance tasks, and portfolio assessment.

Subjective scoring is more susceptible to bias than objective scoring, less reliable than objective scoring, and more difficult to administer than objective scoring.

Ways to minimize the challenges associated with subjective scoring include using clear and specific scoring rubrics, training scorers to use the scoring rubrics consistently, and having multiple scorers score the same responses.

The purpose of test scoring is to assign a numerical value to a test taker's performance, provide feedback to the test taker, and make decisions about the test taker.

Different types of test scores include raw scores, scaled scores, and percentile ranks.

A raw score is the number of correct answers on a test, while a scaled score is a transformed score that takes into account the difficulty of the test.

A percentile rank is the percentage of test takers who scored lower than the individual.

Factors that can affect test scores include the difficulty of the test, the test taker's knowledge and skills, and the test taker's motivation.

Ethical considerations related to test administration and scoring include ensuring that test administrators are trained to administer tests in a fair and unbiased manner, that test scores are used for the purposes for which they were intended, and that test takers have access to their test scores and be able to challenge them if they believe they are inaccurate.

Legal considerations related to test administration and scoring include ensuring that test administrators comply with all applicable laws and regulations, that test scores are kept confidential, and that test takers have the right to due process when their test scores are used to make decisions about them.

Best practices for test administration and scoring include ensuring that test administrators are trained to administer tests in a fair and unbiased manner, that test scores are used for the purposes for which they were intended, and that test takers have access to their test scores and be able to challenge them if they believe they are inaccurate.
